CARRIAGE-BOW.

srncrrrcarron forming part of Letters Patent No. 423,460, dated March18,1890. Application filed August 9} 1889.: Serial No. 320,218. (Nomodel.)

To all whom it may concern:

Be it known that I, ISAAC N. TOPLIFF, a citizen of the United States,residing at Oleveland, in the county of Cuyahoga, State of Ohio, haveinvented. a certain new and useful Improvement in Carriage-Bows; and Ido hereby declare the following to be a specification of my saidinvention.

' My invention relates to leather-covered tubular bow-sockets.

The object of my invention is a construction of bow-socket whereby theedge of the leather covering at the lower endv of the socket may beprotected to save its being roughed and torn by usage, and which alsowill secure at all times a straight edge to the leather covering aroundthe socket at its lower end, and always of uniform distance from the endof the slat-iron, and also form a smooth surface to the socket at thepoint of articulation between the leather covering and slat-iron, thusincreasing the wear of the covering and giving the socket a neaterappearance.

To accomplish the object in view my inven- .tion-consists in certaindetails of construction described herein, and pointed out in the claims.

In the drawings, Figure 1 is a sectional View which illustrates myinvention as adapted tothe main socket of a set of carriagebows. Fig 2is a sectional view of a front or back socket of my invention with theleather cover omitted. Fig.3 is a perspective View of the slat-iron.Fig. 4 is a sectional view of a front or back socket of my inventionwith the leather covering. Fig. 5 is a broken section of the bow=socketheretofore in use, and is introdu'ced to give a clearer understanding ofthe features which constitute my invention.

Heret0fore in the manufacture of tubular bow-sockets the slat-iron hasbeen formed first nearly as illustrated by Fig. 3. It was then insertedin the metaltube and welded,

and after swaging was of the form illustrated by Fig. 5. After weldingand swaging no shoulder was left on the slat-iron, the shoulder havingbeen compressed, and the tube by the process of welding and swagingbeing brought down to the shank of the slat-iron, so

that the socket was tapering to the eye of the slat-iron, as illustratedby Fig. 5. In covering such a socket it is impossible, without trimsocket, to get the edge of the leather straight 1 around the shank or tohave the covers of uniform length in different sockets; besides the rawedge of the leather is left without protection', so that by wear andusage it becomes roughed and torn, so as to present a ragged appearance.

I will now describe my invention.

In the different figures of the drawings, A represents the slat-iron ofthe front and'back sockets.

A represents the slat-iron of the main socket. v p

B is the leather cover.

O is the metal tube, andD is the wood filler.

The slat-iron A of the front and back sockets is formed with a tenon'a',-which enters the metal tube 0 and is brazed or welded in the tube,leaving a shoulder a. broad enough to be flush with the outer surface ofthe leather cover B at the point of articulation.

The filler D is formed and inserted into the socket-tube C in theordinary way. The leather cover B is cut and sewed in any wellknown way,the bottom end being straight, and is then pulled on, after covering thetube with a suitable paste, till the lower end of the cover comes insideof but fits snugly against the extended shoulder a of the slat-iron. Theslat-iron should be made of such shape that when the parts of the socketare assembled a. continuously smooth and tapering form from the upperpart of the socket to the shank of the slatiron will be given.

Themain socket (illustrated by Fig. 1) is provided. with a ferrule E,which is welded, brazed, or driven in the lower end of the metal tube 0and is threaded. The tenon a of the slat-iron A is alsothreaded to screwinto the socket, as shown. The leather cover of the main socket is puton before screwing to it the slat-iron A. Theobjectof screwing in theslat-iron of the main socket instead of brazing or welding it'is thatthe cover may be sewed to its lower end before putting it on the socket.If the slat-iron is united to the socket before putting the cover on,the cover would need to be left open a great partof its length, so thatit could pass over the ears a a and it would afterward have to be sewedby hand when upon the tube. The shoulder ais broad enough to comeflush-with the leather cover as in theothersockets';

It will be observed that in my improved construction of bow-socket theedge of the leather cover is protected, so that it cannot be rubbedagainst and roughed up.v The lower end of the cover can always bemadestraight around the socket and of uniform height from the lower endof the slat-iron in thedif ferent sockets, and that it also presentsabetter appearance-than the leather-covered" socketsof'ptheroonstrue-tions:

What I claim as my invention-is 1. The combination, in a mamage bewyorthe metal tube 0, the wood filler D, theleather" cover B; and the slat-iron projv'ided *w'it-h a such; term th when shoulder" a, and being ofsaid parts: are assembled the soek' n ill becontinu onsly smooth andtapering item: 2 its upper leathencovered part to the shank of the qslatiron; siibstantially described;

2. The combination, 1 in I a main carriage bow, of the metal tube 0, thewoodfiller =D' the fernule E,seeured within the lower end of I the tuheGand havinga female screw-thread,

assembled it will be continuously smooth and tapering over the "point ofarticulation between the said cover and slat-iron to the 'shankof thesl'at iron, substantially as shown and-described; ISAA-G'N. TOPLIFF, iWitness-es V c W.'-'P: Toni),-
